Slotted spring pins are mechanical fastening components used for positioning, alignment, and connection between assembled parts. The split cylindrical structure allows the pin body to compress during installation and generate radial force inside the mounting hole.
For industrial buyers, selecting a slotted spring pins manufacturer requires evaluation of production capability, material options, dimensional control, surface treatment, and customization support. Different applications such as automotive components, machinery, molds, and automation equipment require different pin specifications.

Anhui Pins Metal Products Co., Ltd
CHN-PINS, operated by Anhui Pins Metal Products Co., Ltd, specializes in manufacturing industrial pins and mechanical fastening components for OEM customers. The company produces Slotted Spring Pins, Tooth Spring Pins, Coiled Spring Pins, Dowel Pins, Compression Limiters, Washers, and Retaining Rings for applications requiring controlled positioning and mechanical connection.
As a slotted spring pins manufacturer in China, CHN-PINS focuses on producing elastic cylindrical pins with different diameters, lengths, materials, and surface treatments according to customer requirements.
The company's slotted spring pins feature a longitudinal slot along the pin body. During installation, the pin compresses inside the hole and generates radial expansion force. This structure allows the pin to compensate for minor hole tolerance differences while maintaining contact between assembled components.
CHN-PINS provides custom slotted pins for customers requiring non-standard dimensions. Production processes include raw material preparation, stamping, centerless grinding, heat treatment, surface treatment, and inspection. These processes control the mechanical properties and dimensional consistency of each batch.

How to Choose a Slotted Spring Pins Manufacturer
Selecting a suitable supplier depends on several factors:
Material Selection
Carbon steel is commonly selected for general mechanical assemblies. Stainless steel options are used in applications exposed to moisture or corrosive environments.
Manufacturing Capability
A manufacturer should provide control over:
- Diameter tolerance
- Pin length
- Slot dimensions
- Surface treatment
- Packaging requirements
- Customization Support
OEM buyers often require custom slotted spring pins instead of standard sizes. Suppliers with production flexibility can adjust specifications according to engineering drawings.
